Time is wealth: Part-time work as a means to foster sustainable lifestyles?

Under which circumstances does a reduction of working time lead to a more sufficient lifestyle? How does a reduction of working hours affect employees’ well-being? What implications do flexible working models have for employers? And which economic, legal, and political framework conditions must be taken into consideration? The research project “Time is wealth: Part-time work as a means to foster sustainable lifestyles?” aims to provide in-depth insights into these and further questions.

Closing a research gap

The reduction of working hours is increasingly being put forward in the debate on how to foster society’s transformation to sustainability. Indeed, evidence shows that it might facilitate more sufficient lifestyles: Macro-level studies in various countries have established links between shorter working hours and a lower environmental impact. However, very few empirical studies so far have examined the connections between the following factors:

  • The amount of working hours
  • Consumption patterns and their impacts on the environment
  • Individual well-being

The project intends to close this research gap. Using different methodological approaches, it explores to what extent a self-determined reduction of working hours can help to reduce consumption-related environmental impact in the Swiss context – while maintaining or even increasing employees’ (subjective) well-being.

Most important results


Working less usually means earning less income, but having more time that is not bound up by gainful employment. Previous studies have assumed that the corresponding income effect – i.e. earning less – would have positive consumption-related impacts on the environment. However, these are sometimes offset by the negative environmental impacts of increased leisure activities.

Project interviews with people who reduced their working hours showed that environmentally friendly lifestyle changes were more likely when newly acquired time was used for previously planned activities, e.g. for parenting, continuing education, or social engagement. By contrast, increased consumption was more likely among those who decreased their working hours primarily to reduce stress and to gain more free time.

Lower income – more sufficient lifestyles

So how do the consumption patterns of part-time and full-time workers differ? A large-scale study conducted in the project confirmed the importance of the income effect: employees who worked fewer hours displayed more sufficient lifestyles according to various indicators. These indicators – such as spending on clothing, home size, frequency of air travel, and extent of vehicle use – could mainly be explained by these participants’ lower incomes.

Part-time workers also commuted less by car – not because of their lower income, but rather thanks to having more free time.


The study further shed light on what changes when people reduce their working hours. Indicators of well-being – especially life satisfaction in the short term, but also stress-related burnout symptoms in the short and medium term – improved following a reduction in working hours. The study also showed that these participants’ car commuting times decreased while their environmentally friendly behaviour increased – two indicators that can be attributed to a time effect rather than an income effect. Meanwhile, consumption-oriented spending on clothing declined as a result of lowered earnings.

Less car commuting – greater well-being

Despite participants’ working time reduction, a variety of other environmentally crucial indicators remained stable over the study’s nine-month observation period, in particular general vehicle use, air travel, and home size. This suggests that such structurally determined behaviours are relatively fixed and that possible impacts of working less may only emerge over a longer period.

The positive effect of reduced car use is interesting, however. Not only was it associated with decreased environmental impacts, but it could also be a measure to increase well-being. Last but not least, the study results showed that many people desire to work less.


Based on a comprehensive literature review and conceptual work, the project considered the implications of reducing working hours in Switzerland.

  • The project’s first key finding is that the ecological, social, and economic effects of reduced working hours must be carefully assessed and compromises must be found. One way of balancing the social and ecological impacts of reduced working hours would be providing progressive wage compensation. In this way, lower-income workers would not suffer additional wage losses. Instead, the measure would particularly target those in high-income brackets, who tend to have the worst ecological footprints.

  • The project’s second key finding is: There are many possible accompanying measures that could lead to a reduced standard workweek in the long run, building on the engagement of various actors.
  • Finally, the third key finding is that the economic feasibility of reduced working hours represents a major sticking point and one of the biggest concerns among various stakeholders.

The project succeeded in identifying initial action strategies for the concrete design and economic feasibility of a workweek reduction, but could not provide conclusive answers. There is significant need for more research in this area, as echoed by a variety of actors with whom the results were discussed.

In a corresponding literature review, the ecological, social, and economic impacts of different forms of work reduction are examined.

Weniger arbeiten, zufriedener leben

«Erstaunlich ist, dass die Leute trotz des Einkommensverlusts nicht weniger zufrieden waren als mit mehr Geld»: CDE-Wissenschaftlerin Stephanie Moser zu Studienresultaten über die freiwillige Arbeitszeitreduktion.

Weniger arbeiten – Klimakrise bekämpfen

Wenn wir mit immer weniger Arbeit immer mehr produzieren und gleichzeitig beim gleichen Arbeitspensum bleiben, würden Produktion und Umweltbelastung deutlich steigen, so Sebastian Neubert, wissenschaftlicher Mitarbeiter am CDE, im Interview zu den Wechselwirkungen von Arbeit und Nachhaltigkeit. Gleichzeitig führe die viele Arbeit insbesondere in der Schweiz zu immer höheren Einkommen, die ihrerseits den Konsum ankurbeln würden und damit auch die Umweltbelastung.

Mit mehr Freizeit gegen die Klimakrise

Kürzere Arbeitszeiten dienen dem Klima. Zumindest ein Teil des Effekts hat laut CDE-Wissenschaftlerin Stephanie Moser damit zu tun, dass die Einkommen sinken würden – denn Grossverdienende verursachen im Schnitt besonders viele Treibhausgasemissionen. Die Forschenden des CDE schlagen deshalb vor, dass nur die hohen Einkommen sinken sollen.

Um genügsam zu werden, müssen wir wissen, was uns gut tut

Wie kann man ein suffizientes Leben schmackhaft machen? - Auf diese Frage antwortet Stephanie Moser vom CDE: «Auf der einen Seite, indem wir unsere Lebenswelten neu arrangieren: Wie wir unsere Wohnungen bauen, unsere Quartiere gestalten, welche Angebote uns in Läden zur Verfügung stehen oder wie mobil wir sind. Andererseits hängt Suffizienz stark damit zusammen, wie viel Zeit wir haben, um zu reflektieren, was uns gut tut.»

Zeit für Wandel. Mit weniger Arbeit in die Zukunft

Wir produzieren immer mehr mit immer weniger Arbeit. Statt mehr zu konsumieren, könnten wir als Gesellschaft unsere Arbeitszeit reduzieren.
